Understand GOPATH

21 September 2014

GOPATH can also be called go workspace

the structure of GOPATH contain three folder, –src –pkg –bin where src is for source code, pkg is for dependence and bin is for binary file

a tipical structure of go project

bin/
    streak                         # command executable
    todo                           # command executable
pkg/
    linux_amd64/
        code.google.com/p/goauth2/
            oauth.a                # package object
        github.com/nf/todo/
            task.a                 # package object
src/
    code.google.com/p/goauth2/
        .hg/                       # mercurial repository metadata
        oauth/
            oauth.go               # package source
            oauth_test.go          # test source
    github.com/nf/
        streak/
            .git/                  # git repository metadata
            oauth.go               # command source
            streak.go              # command source
        todo/
            .git/                  # git repository metadata
            task/
                task.go            # package source
            todo.go                # command source

the command go install, will build go executable and put it into bin folder and when you go get ..., it will clone the project from github into src folder of your workspace aka GOPATH
